"AODs indicate whether the Service will follow a significant adverse opinion of the Tax Court, a district court, Court of Federal Claims, a bankruptcy court, or an appellate court. The recommendation, which is published in the Internal Revenue Bulletin, is characterized as an acquiescence, a nonacquiescence, or an acquiescence in result only.

The consolidation appears in the first Bulletin for July and in the Cumulative Bulletin for the first half of the year. The annual consolidation appears in the first Bulletin for the following January and in the Cumulative Bulletin for the last half of the year. " (Publication of Actions on Decisions, IRM §
